Imputation and derivation

Derivation

Calculated from the century month code (CMC) of the respondent's date of birth (V011) and the CMC of the date of interview (V008). In a few cases the age in the data file will be different from that reported by the respondent when the respondent's birthday was during the month of interview, but she had not yet had her birthday. If the respondent correctly reported her age at her last birthday (and not her age at her next birthday) then the calculated age was rounded up from the reported age, to avoid inconsistencies between the age and the CMC for the birth.
